Creation

Face_base f;
	Default constructor.
Face_base f ( void* v0, void* v1, void* v2);
	Constructor setting the incident vertices.
Face_base f ( void* v0, void* v1, void* v2, void* n0, void* n1, void* n2);
	Constructor setting the incident vertices and the neighboring faces.

Access Functions

bool	f.is_constrained ( int i)
		Returns true if the edge between fand its neighbor \ccVar.neighbor(i is constrained. Precondition: .

Modifiers

void	f.set_constraint ( int i, bool b)
		Sets the edge between fand its \ccVar.neighbor(i) as a constrained or unconstrained edge according to b.
void	f.set_constraints ( bool c0, bool c1, bool c2)
		Sets the status (constrained or unconstrained) of the three edges of f.

Miscellaneous

bool

f.is_valid ()

Calls F::is_valid() and additionally checks if the edges of fare consistently marked as constrained or unconstrained edges in face fand its neighbors.
